SHAFAQNA – Imam Ali (AS) said: Be ready for death; May God forgives you that the call to leave (this world) will be proclaimed among you. Reduce the attachment to this world, and return to the hereafter with good provision because there is a difficult pass and terrifying halting-places ahead of you which you must go through and stop there. Be aware that the gaps between the looks of death towards you are short, and it seems that its claws have been sunk in your bodies. The difficult tasks of this world have made you neglectful of death, and have kept hidden its unbearable calamities from you. Therefore, cut your attachments to this world, and get help from piety .
 Nahjul Balaghah, Sermon 204.
